Control modules handle long ranges

The Wi.232FHSS-250-R modules combine a low-power transceiver with a powerful multipoint-to-multipoint frequency hopping spread spectrum (FHSS) protocol controller

A new family of Radiotronix long-range embedded modules based on the Analog Devices ADF 7020 transceiver IC is now available from Solid State Supplies. The communications networking capability of the Radiotronix Wi.232FHSS-250-R embedded module for long-range wireless control, remote monitoring and sensing applications makes it suitable for applications in industrial, medical, transportation, oil and gas, wireless sensing, security, consumer and automatic meter reading (AMR).
The Wi.232FHSS-250-R modules combine a low-power transceiver with a powerful multipoint-to-multipoint frequency hopping spread spectrum (FHSS) protocol controller to form a complete wireless communication solution.

Among the many new features are 250mW on board PA, automatic gain control (AGC) with six intermediate gain steps and four module override settings, variable power output control with four steps from +8 to +23dBm output and two digital RSSI registers and one analogue RSSI output.

Supporting a wide range of data rates, allowing a designer to tune the module's performance to meet the application's throughput and range requirements, the Wi.232FHSS-250-R modules employ frequency hopping spread spectrum modulation.

Designers can program the module to use one of six hopping sequences.

The component family also supports four different addressing schemes: peer-to-peer, 32bit user-assigned, 16bit user-assigned and MAC.

User-assigned addressing modes incorporate masking to allow the formation of subnets which allow the device to operate co-located networks with minimal interference.
